Proportional valve driver

PVD3DIN electronic amplifier drives any open-loop single solenoid proportional valve rated from 0.5 to 3 A. Three-digit display shows the input signal or the output current and serves as a tune-up interface. The input signal can be selected from 0-5 V, 0-10 V, 0-20 mA or 4-20 mA. It remains completely sealed even during set-up. The only tool required for installation and tune-up is a Philips #1 screwdriver.
